Further, in order to realize image procossing, one master cpu can be set in picture pick-up device, for the intensity of illumination obtained according to described intensity of illumination sensor, the image that described photographic head is shot processes, a display can be set simultaneously, for the image after processing is displayed。
Can certainly being that picture pick-up device is merely responsible for Image Acquisition and intensity of illumination and obtains, then pass to external processor in real time and display carries out the display that processes, concrete operation and implementation, the application be not construed as limiting。
Based on the picture pick-up device shown in Fig. 1, additionally provide a kind of shooting display packing in this example, as in figure 2 it is shown, comprise the following steps:
Step 201: obtain the image shot by photographic head；
Step 202: obtain the intensity of illumination of shooting environmental when shooting described image；
Step 203: described image is displayed according to the intensity of illumination of described shooting environmental。
Considering the mode that can the adopt feature extraction characteristic information from extracting target from images object, then, the characteristic information of combining target object determines that together with intensity of illumination a suitable pixel value carries out image and shows。I.e., it is possible to the destination object in image is carried out feature extraction, then according to the feature extracted and described intensity of illumination, image is displayed。
So that the display effect of image, it is possible to destination object is adopted different pixel values with the region except destination object, so can so that destination object is more prominent, to strengthen display effect。Specifically, it is possible to perform according to following steps:
S1: obtain the pixel value being extracted feature；
S2: intensity of illumination is digitized as illumination intensity value；
S3: pixel value and illumination intensity value are fitted, obtains the pixel value in described image region except described destination object；
S4: described image is displayed, wherein, the pixel value that described image region except described destination object obtains according to matching displays。

S2: extracted the skin pixel value collecting human body in image by feature extracting method, it is also possible to be the pixel value of other image；
S3: illumination intensity value and skin pixel value are carried out classification division process respectively；
For example, illumination intensity value and skin pixel value have a scope, such as: (0,255)。This scope is carried out equivalent division by so-called staged care exactly。In theory, division more thin, the precision of process is more high, but divide more thin, the computational load of CPU is more big, and the fluency that system is run is more low。Therefore, in order to prevent, hardware resource configuration is inadequate, improve system fluency, it is possible to be divided into 16 deciles。
S4: by skin pixel value and environment illumination intensity value, matching draws the pixel value of image display background, draws real-time image display background best pixel value；
In this example, matching is exactly compensated value according to two numerical value (illumination intensity value and skin pixel value), in order to the brightness of background image is adjusted, wherein it is possible to pass through formula or the mode tabled look-up is compensated value。If adopting the mode tabled look-up, then corresponding form can be set up according to experiment experience value。Such as, if be detected that intensity of illumination is 80, the skin pixel value of image is 100, it is seen that two numerical value relatively, if displayed according to this numerical value, then the contrast demonstrating image will be poor。Table look-up by inputting the two parameter, it can be deduced that background luminance offset is-30, and then, background luminance is dimmed by system by image automatically with the ratio of-30, thus increasing the display effect of people。
When reality realizes, it is assumed that having an image, have individual, then people shows according to normal mode in image, the region except people shows according to the background best pixel value obtained, thus increasing the display effect of people。
S5: carry out image procossing according to the human body image drawn and background image value and show。
Namely, display effect is strengthened with the mode integrated by image segmentation, it is worth best background pixel value to carry out integration process in conjunction with illumination intensity value and skin pixel, draw best results image, so that image has sensing external environment and regulates the ability of image, it is possible to provide the user the image information that visual impression is strong in real time。Further, strengthen image effect by regulatory function, improve recognition accuracy。Such as, when the method is applied to gesture recognition system time, display effect is adjusted by the colour of skin according to identifying human body, it is possible to strengthen the colour of skin of display human body。
